DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a shielded ribbon cable used for electric wiring of electronic equipment and the like.
Things.

[0002]

2. Description of the Related Art A shielded ribbon cable and a method of manufacturing the same are disclosed in Japanese Unexamined Patent Publication No.
There are a number of known examples such as 66333, and the known examples are plate-like bodies in which a plurality of groups of insulated coated cores and ground wires of the coated cores are arranged in parallel at a required pitch. The shield ribbon of metal foil is laminated above and below the covered core wire group and the ground wire of the exposed conductor, and the jacket layer is further laminated on the shield layer. Manufactured as a cable.

[0003] The long ribbon cable is cut to a required cable length on the wiring, the shield layer and the jacket layer at a part of both ends of the cut ribbon cable are peeled off and the coated core wire is covered. The conductor is exfoliated to expose the conductor, and the exfoliated conductor group and the ground wire are formed into a slightly protruding terminal connection portion. Then, a terminal processing method of connecting and wiring the terminal connection part to the other party is adopted.

[0004]

In the above-described shielded ribbon cable of the prior art, when the terminal connection portion is processed and formed in the final step, a shield layer and a jacket are formed on the portion to be formed at the terminal connection portion. Since the layers are laminated and the parallel pitch of the group of insulated core wires changes in various ways, the work of cutting and removing only the unnecessary portions of the shield layer and the jacket layer is extremely complicated,
There is a problem that a special processing process and processing equipment and processing jig become indispensable, and the molding cost of the terminal connection part is increased. Even if the terminal connection is formed by hand, it takes a lot of man-hours and is inefficient, and the shielded ribbon cable having a required cable length and the terminal connection is ready for use. There is a disadvantage that the moldability in mass production is inferior. The present invention is directed to a shielded ribbon that solves the above-mentioned drawbacks of the prior art .
A method for manufacturing a cable is provided.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned technical problems, the present invention provides a method of connecting an insulated core wire group and a ground wire to a required parallel connection.
It is possible to form a wire group plate
In the continuous progressive step, the longitudinal direction of the wire group plate
Insulation is melted on the upper and lower surfaces of the electric wire group plate at arbitrary intervals in the
A band-shaped fixing part is formed intermittently by attaching
Except for the entirety of the fixing portion or both edges in the front-rear direction.
The upper and lower surfaces of the electric wire group plate, leaving most of the fixing portion
Then, a shield tape is stuck, and then,
Cut the middle, have the required cable length, and cut
A terminal connecting portion forming portion formed by each half of the fixed portion is
Method of manufacturing shielded ribbon cable exposed at both ends "
Is the feature.

The sheet formed by the above-described manufacturing method is
In the post-process, the ribbon cable with
The conductor is exposed by peeling off the insulation coating at the part where the connection is to be formed
The terminal connection portion is formed, the ready-to-use state shield
Made with attached ribbon cable.

[0007]

The shielded ribbon cable according to the present invention described above
Are to be formed on both upper and lower surfaces of the wire group.
Exposed from the attached shield tape, the terminal connection
During the forming process, a sheet that interferes with workability
Easy to process terminal connection because no tape
No special processing process, processing equipment and processing jig
Be useful. Then, during the continuous progressive process of the wire group plate,
Attachment part formation position ・ Shield tape attachment position ・
At the cable cutting position, formation of a fixed part and sealing
Tape bonding and cable cutting are sequentially and continuously performed.
Therefore, shielded ribbon cables of the required cable length
And efficient continuous molding.
